How do I add Colour to my signs when I can not paste §

I bought the colour sign command but can not get the colours.

is there another way to insert the symbol? §

I have tried
ALT SO is how I use it in other programs and it works here but not in game?
cntl+shift+U+A+7

I don't have a numpad on my keyboard

Even tried adding these to my Arduino key/mouse combo board

Any one using Linux get something to work?

 

you use & instead so
